How boot Alpine Linux

[linmob]

pmOS uses different initram and they are going systemd.

Maybe read the announcement[url=https://postmarketos.org/blog/2024/03/05/adding-systemd/][/url] again, it's already in the title: They are adding systemd, not switching to it. And:

Don't worry, as long as OpenRC is in Alpine Linux (on which postmarketOS is based), you will still be able to select it in pmbootstrap when building your own images.

Now, granted, that's from March. But nothing changed since, and, even at this point in time, you really need to jump through some hoops if want to use systemd with Alpine. All standard images are still "systemd free" if you will.

Also they cannot use btrfs + FDE, right?

I know that pmbootstrap install has a --filesystem option. I've never tried it, but I don't see why combining --fde and --filesystem btrfs should be impossible; so maybe just try

Code:

pmbootstrap install --fde --filesystem btrfs

Hope this helps!
